This book presents the combined proceedings of the 7th International Conference on
Computer Science and its Applications (CSA-15) and the International Conference on
Ubiquitous Information Technologies and Applications (CUTE 2015), both held in Cebu, Philippines, December 15 - 17, 2015.

The aim of these two meetings was to promote discussion and
interaction among academics, researchers and professionals in the field of
computer science covering topics including mobile computing, security and trust
management, multimedia systems and devices, networks and communications,
databases and data mining, and ubiquitous computing technologies such as ubiquitous communication and networking, ubiquitous software technology, ubiquitous systems and applications, security and privacy.

These proceedings reflect the state-of-the-art in the development of computational
methods, numerical simulations, error and
uncertainty analysis and novel applications of new processing techniques in
engineering, science, and other disciplines related to computer science.
